Mike I have no idea of your configuration other than its sorta like the GUE rigged JJ with backmounted 50s but uses a 40 of offboard O2 and does not use an orifice or a solenoid or run entirely manually like the UTD Kiss. So I have no idea what you are doing with what CCR.
Perhaps a photo or description or reference to someone else's configuration would be helpful.
